OnMainThreadJobManagerRunnerRegistry

public OnMainThreadJobManagerRunnerRegistry(JobManagerRunnerRegistry delegate,
                                            org.apache.flink.runtime.concurrent.ComponentMainThreadExecutor mainThreadExecutor)

方法详细资料

isRegistered

public boolean isRegistered(org.apache.flink.api.common.JobID jobId)

从接口复制的说明: JobManagerRunnerRegistry

Checks whether a JobManagerRunner is registered under the given JobID.

指定者:

isRegistered 在接口中 JobManagerRunnerRegistry

参数:

jobId - The JobID to check.

返回:

true, if a JobManagerRunner is registered; false otherwise.

register

public void register(JobManagerRunner jobManagerRunner)

从接口复制的说明: JobManagerRunnerRegistry

Registers the given JobManagerRunner instance.

指定者:

register 在接口中 JobManagerRunnerRegistry

get

public JobManagerRunner get(org.apache.flink.api.common.JobID jobId)

从接口复制的说明: JobManagerRunnerRegistry

Returns the JobManagerRunner for the given JobID.

指定者:

get 在接口中 JobManagerRunnerRegistry

另请参阅:

JobManagerRunnerRegistry.isRegistered(JobID)

size

public int size()

从接口复制的说明: JobManagerRunnerRegistry

Returns the number of JobManagerRunner instances currently being registered.

指定者:

size 在接口中 JobManagerRunnerRegistry

getRunningJobIds

public Set<org.apache.flink.api.common.JobID> getRunningJobIds()

从接口复制的说明: JobManagerRunnerRegistry

Returns JobID instances of registered JobManagerRunner instances.

指定者:

getRunningJobIds 在接口中 JobManagerRunnerRegistry

getJobManagerRunners

public Collection<JobManagerRunner> getJobManagerRunners()

从接口复制的说明: JobManagerRunnerRegistry

Returns the registered JobManagerRunner instances.

指定者:

getJobManagerRunners 在接口中 JobManagerRunnerRegistry

localCleanupAsync

public CompletableFuture<Void> localCleanupAsync(org.apache.flink.api.common.JobID jobId,
                                                 Executor executor)

从接口复制的说明: LocallyCleanableResource

localCleanupAsync is expected to be called from the main thread. Heavy IO tasks should be outsourced into the passed cleanupExecutor. Thread-safety must be ensured.

指定者:

localCleanupAsync 在接口中 LocallyCleanableResource

参数:

jobId - The JobID of the job for which the local data should be cleaned up.

executor - The fallback executor for IO-heavy operations.

返回:

The cleanup result future.

unregister

public JobManagerRunner unregister(org.apache.flink.api.common.JobID jobId)

从接口复制的说明: JobManagerRunnerRegistry

Unregistered the JobManagerRunner with the given JobID. null is returned if there's no JobManagerRunner registered for the given JobID.

指定者:

unregister 在接口中 JobManagerRunnerRegistry

getWrappedDelegate

public JobManagerRunnerRegistry getWrappedDelegate()

Returns the delegated JobManagerRunnerRegistry. This method can be used to workaround the main thread safeguard.

指定者:

getWrappedDelegate 在接口中 org.apache.flink.util.WrappingProxy<JobManagerRunnerRegistry>
